The Radio Warfare Project
In 1955 the CSF company in France developed, produced and sold freely the Carcinotron tube. It was immediately realized that this tube could readily be used as the power source of a noise jammer which could be used against the existing Canadian defence radars.
It was decided to establish in DRTE a Radio Warfare Section (referred to in one issue of the DRB Newsletter as the Radio Welfare Section) with the objective of funding what "quick fixes" could be applied to the radars. Again we found ourselves in the position of building up a group, with. very little expertise on which to base its work. Indeed Roy Dohoo (who was the section leader) and Frank Smith were the only two members of the section who had had any radar experience - and that was over ten years earlier during the war. Several other members of the staff of the old (microwave) fuze section moved into the radar work and within a couple of years some success had been achieved. Again during these years cooperation with the USA and the UK was close - British aircraft were flown to North America for trials and "Ground Band Monitors", developed at DRTE were made available to the British. During these years, too, we had close collaboration with NRC - and especially with Bill Brown and Bill Haley - where radar work had continued from the very large effort which was deployed in World War II.
Again, industry was closely involved and some success was achieved in the sale of counter-counter-measure equipments.
